Coordinate grid with x and y from -5 to 5; shape S is a trapezium with vertices (2, 1), (2, 2), (4, 4) and (4, 1)

(a) On the grid above, translate shape S by 1 square to the left and 3 squares down. (1)

Coordinate grid with x from -5 to 5 and y from -6 to 6; triangle T with vertices (2, 1), (4, 1) and (4, 4)

(b) On the grid, rotate triangle T 90° clockwise about (0, 2). (2)

Notes

B2: (B1 for a rotation of 90° clockwise about a different centre i.e. a triangle in the same orientation as the correct triangle
or
rotation by 90° anticlockwise about (0, 2))
